tomato wl520gu connected as client bridge and print server to at&t 2wire uverse router. i can successfully print, telnet, and access the tomato gui from the wan by port forwwarding on the 2wire to tomato. i want to set up a port forward (br0-br0) on the tomato to reflect incoming traffic on 8081 to the 2wire gateway port 80. ive read ddwrt adn tomato wiki but i can't figure out an iptables command to do this.
